Proximity facet: show post distance

When using the proximity facet, it’s now possible to show each post’s distance from the specified location.

Enable distance

Storing each post’s distance requires a little extra memory, so it’s disabled by default. To enable it, add the following to your theme’s functions.php:

add_filter( 'facetwp_proximity_store_distance', '__return_true' );

Show distance

Next, use the facetwp_get_distance function to display the distance for each post. It returns the numeric distance if the proximity facet is in use, or FALSE.

<?php
$distance = facetwp_get_distance();
if ( false !== $distance ) {
    echo round( $distance, 2 );
}
